Shield of the Fleet
Aegis is an integrated missile guidance system used on U.S. Navy and allied ships to protect the battle group.
The Aegis SPY-1 radar acquires and tracks multiple targets, such as enemy planes and missiles, and helps defend against them. It can operate as an integrated single ship system, as well as in a ship-to-ship network.

The SPY-1D(V) is a high-powered transmitter that is combat proven and shock reliable. It supports search, track and missile guidance functions.
